To answer your initial question: Yes, therapy is the one sure thing that anchors me. I know that my T is there for me. He's had to cancel every once in awhile (less than me). Life is full of happenings and just about everyone has gotten sick or had to deal with something along the way. Life is messy. There are things that happen that we have no control over, no matter who we are or what our job title is.

Is your T's situation temporary or likely to be ongoing? Do you want to continue with your T if the issue is going to be long-term? If you have issues with change, will you be able to adjust to permanent change? Maybe your T is saying that this can be a way for you to learn to adapt to change. Obviously your T is aware that this situation is difficult for you. Can you continue this discussion with her?
